STEAli/lm-HEATNG APPARATUS.

SPECIFICATION forming partei' Letters Patent No. 344,645, dated June 29,1886.

Application filed November 3, 1385. Serial No. 181,741. (No model.)

To aZZ whom it may concern,.-

Be it known that I, J AMES J. FLYNN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,haveinvented certain new and useful Improvements in Steam- HeatingJApparatus; and I hereby declare the following to be a full, clear, andexact description of the same.

My invention relates to that class of apparatuseswh'erein the heatingmedium is obtained by t-he combustion ot' a hydrocarbon oil, forming thefuel-supply introduced to the heatingchamber by means of a suitableinjector; and

. my invention relates more particularly to the application of asteam-heating apparatus of the description above outlined for use onstreetrailway cars.

It is the principal object of my invention, though its use, as willhereinafter be pointed out, is not limited to such end, to provide ahydrocarbon steanrheating apparatus for use on street-railway cars,whichshall obviate the disadvantages heretofore incident to the employment ofwarming devices with such vehicles, and which shall accomplish thedesired end by means of a non-obstructing, compact, simple, inexpensive,and. inexpensively operative mechanism.

My invention consists in the general coustruction of my improved deviceand in certain details of construction and combinations of parts formingthe same, all as hereinafterv more fully set forth.

Referring to the drawings,-l `igure l is a sec tional plan view lakenjust below the roof of a street-railway car provided with my improvedheating apparatus, and showing in dotted lines the arrangement of theradiating coils; Fig. 2, a vertical longitudinal sectional view of aportion of a street-railway car, showing a boiler and other details inposition; Fig. 3, a cross-section of boiler, jacket, and steamsuperheating device, taken near the steamdome, and showing the latter inelevation; Fig. 4, a central cross-section through the roofofastreet-railway car, showing in elevation the water-supply tankcontained therein; Fig. 5, a detail view showing a broken portion of theinjector; Fig. 6, a perspective view showing nozzle of injector; Fig. 7,a view similar to Fig. 2, taken behind the lat-ter, and showing a coilofpipe employed as a steam-superlheater; and Fig. 8 a sectional View ofa portion of a street-railway car, showing in elevation beneath the seata coil of pipe arranged to form a vertical coil-radiator, instead of thehorizontal coilradiator shown by dotted li nes in Fig. l.

A represents the frame-work of a streetrailway car, toward the upperportion ofwhich, in one corner or in diagonally-opposite corners, asshown, are placed boilers B, preferably about tive feet in length andeight inches in diameter, and provided each with ajacket, C, (shown inFigs. 2, 3, and 7,) completely surrounding the boiler, but dividedlongitudinally by a partition, C', (see Fig. 3,) fitting closely aroundthe boiler, and affording between the said partition and the lowerportion of the jacket a combustion-chamber, which is again divided by alateral partition, C2, (sce Fig. 2,) near the front end of the boilerand extending from the lower part of the jacket to the partition C. Anoil-burner in the 'form of an injector, D, hereinafter described,extends through the partition C2 for each boiler, and the hot productsof combustion from the burning hydrocarbon oil pass through thecombustion-chamber around the lower portion ofthe boiler, ,following thecourse ofthe arrows, as indicated in Fig. 2, are returned by way ofi'lues t within the boiler, and pass again over its upper surface, toescape thence through a stack, r.

E is a water-supply tank contained within the upper central portion ofthe carin the compartmentusually occupied by the lantern, and arrangedto leave spaces .r between itand the windows ordinarily provided in thispart of the car, to avoid obstruction to the ventilation. The tank' Ecommunicates with the boilers through supply-pipes q, having checkvalvesq, and is provided with a removable cap, p, by removing which the tankmay be filled through the roof of the car, and suitable cocks, q2, areprovided upon the tank E to permit escape of air while the latter isbeing filled.

A steam-dome, F,of common construction,

is provided upon each boiler, B, and extends through the jackets C,above which it communicates through a pipe, o, passed downward near thecorner of the car, withv a radiating coil, G, beneath the seat, whichcoil may be arranged either horizontally, as shown by the dotted linesin Fig. 1, or vertically, as shown by full lines in Fig. 8, as desired,and a pipe, o', passing upward near the pipe 0, and communicating withthe water-supply tank, returns to the latter the steam from the coils,which serves to heat the contents of the supply-tank, and thuscompletely utilizes all the heat generated and avoids waste of Water.

A blow-off cock, a, is provided upon each coil G, forv the usualpurpose, and check! valvesm, upon the pipes o, prevent backset from thewater-supply tank.

If desired, the pipe o may be led back into the combustion-chamber, asshown in Figs. 3 and 7, and bent into the form of a superheating-coil,I-I, which affords advantage in the way of superior economy.

In diagonal corners of the car, toward the upper portion of the same andopposite the boilers B, are placed oil-supply tanks I, one for eachboiler, and communicating with injectors D, hereinbefore mentioned, byway of pipes Z, which latter form the casings for the injectors andextend through the partitions C2 into the combustion-chambers in theform of flattened lips Z. (See Fig. 6.) A steamsupply pipe, k,communicating with the dome F, enters the injector D. as shown in Figs.2 and 5, and impels the hydrocarbon oil into the combustion-chamberthrough the lip Z in the form of a tine spray, and perfect control ofboth steam and oil supply is afforded by means of suitable cocks in eachpipe Z and k.

To start the vdevice,a door (not shown) is provided in the jacket Gadjacent to the nozzle of the injector D, through which lighted paper orother suitable lighting medium may be inserted.

As hereinbefore mentioned, my device is not limited to its applicationas a heating apparatus for street-cars, but affords advantages whereverit is desired to maintain an equitable temperature in an apartment atmoderate cost and under conditions hereinbefore specified. Forthesereasons my device is also well adapted for use with incubators,hot-houses, conservatories, and the like.

Vhat I claim as new, and desire to secure by Letters Patent, is

l. The combination, with a compartment to be heated, of a boiler, B,ajacket, C, containing the boiler and forming the combustion-chamber,and supported adjacent to the roof of the said compartment, aradiatingcoil, G, in the lower part of the compartment, a steam-dome, F,with which the coil G communicates, a water-reservoir, E, supportedcommunicating with the superheating-coil, a p

water-reservoir, E, supported within the said compartment adjacent tothe roof thereof,and communicating with the boiler and with thedischarge end of the coil G, and a suitable oilburner for generatingsteam in the boiler with liquid fuel, substantially as set forth.

3. The combination, with a compartment to be heated, of a boiler, B, ajacket, O, containing the boiler and forming the combustionchamber, andsupported adjacent to the roof ofthe said compartment and provided withastack, r, a radiating-coil, G, in the lower part of the compartment, asteam-dome, F, with which the coil G communicates, a water-reservoir, E,supported within the said compartment adjacent to the roof thereof, andcommunicating with the boiler and with the discharge end of the coil G,an oil-reservoir, l, supported within the said compartment adjacent tothe roof thereof, and an injector, D, with which the reservoir Icommunicates, which extends into the jacket C and communicates with thesteam-dome, substantially asA described.

4. The combination, with a compartment to be heated, ofa boiler, B,ajacket, C, containing the boiler and forming the combustionchamber, andsupported adjacent to the roof of the said compartment and provided witha stack, r, a steam-superheating coil, H, within the jacket C, asteam-dome, F, with which the coil I-I communicates, a radiating-coil,G, in the lower part of the compartment communieating with thesuperheatingcoil, a waterreservoir, E, supported within the saidcompartment adjacent to the roof thereof, and communicating with theboiler and with the discharge end of the coil G, an oil-reservoir, I,supported within the said compartment adjacent to the roof thereof, andan injector, D, with which the reservoir I communicates, which extendsinto the jacket C and communicates with the steam-dome, substantially asdescribed.
